Hello rithish,

try opening the sql command line and connecting to your database, e.g

Conn system as sysdba

and extremely thnak u i was searching for 3 hours and i have more doubts ill post it to u in next thread

difference between

conn system

conn system as sysdba

actually i created a table in conn system.and next time i logged in as conn system as sysdba.i could not view the table

You can't log in with

conn system as sysdba

it has to be

conn sys as sysdba

if you want to login as system login with system/<password>@<connection_string>
